Plotly Offline¶

Plotly Offline brings interactive Plotly graphs to the offline (local) environment.

Instead of saving the graphs to a server, your data and graphs will remain in your local system. When you're ready to share, you can just publish them to the web with an online Plotly account or to your company's internal Plotly Enterprise.

To get started with Plotly Offline, upgrade to the 1.9.x series:

In [1]:

! pip install plotly --upgrade

Requirement already up-to-date: plotly in /anaconda/lib/python2.7/site-packages
Requirement already up-to-date: requests in /anaconda/lib/python2.7/site-packages (from plotly)
Requirement already up-to-date: six in /anaconda/lib/python2.7/site-packages (from plotly)
Requirement already up-to-date: pytz in /anaconda/lib/python2.7/site-packages (from plotly)

In [2]:

from plotly import __version__
from plotly.offline import download_plotlyjs, init_notebook_mode, iplot

print __version__ # requires version >= 1.9.0

1.9.5

You can plot your graphs from a python script from command line. On executing the script, it will open a web browser with your Plotly Graph drawn.

In [3]:

from plotly.offline import plot
from plotly.graph_objs import Scatter

plot([Scatter(x=[1, 2, 3], y=[3, 1, 6])])

You can also plot your graphs offline inside a Jupyter(IPython) Notebook Environment. First you need to initiate the Plotly Notebook mode as below:

In [4]:

init_notebook_mode() # run at the start of every ipython notebook to use plotly.offline
                     # this injects the plotly.js source files into the notebook

In [5]:

iplot([{"x": [1, 2, 3], "y": [3, 1, 6]}])

In [6]:

from plotly.graph_objs import *
import numpy as np

In [7]:

iplot([Box(y = np.random.randn(50), showlegend=False) for i in range(45)], show_link=False)

In [8]:

x = np.random.randn(2000)
y = np.random.randn(2000)
iplot([Histogram2dContour(x=x, y=y, contours=Contours(coloring='heatmap')),
       Scatter(x=x, y=y, mode='markers', marker=Marker(color='white', size=3, opacity=0.3))], show_link=False)
